About John B. Larson's congressional trading

John B. Larson Stock Trading Activity | Quantellect John B. Larson Stock Trading Activity

John B. Larson's disclosures show a trading pattern dominated overwhelmingly by exits. Across 252 transactions on file, 191 are sales against just 59 purchases. Transactions dated December 18, 2019 form an especially broad sale event: they were disclosed together on January 31, 2020, and were associated with a Fidelity Investments SEP IRA. That filing touched Apple, Microsoft, Danaher, Fortive, Home Depot, Costco, JPMorgan Chase, Mastercard, and more, spanning technology, health care, industrials, consumer businesses, financials, energy, materials, and real estate. The result is a broad, cross-sector wave of sales within the SEP IRA.

The transaction-date record runs from August 14, 2012 through December 18, 2019, with no transactions on file after that date. Activity intensified toward the end of the period rather than tapering off: 2019 alone accounts for 62 transactions (3 purchases, 59 sales), 2018 shows 55 (9 purchases, 46 sales), and 2017 shows 38 (6 purchases, 30 sales, plus 2 other-type transactions). Earlier years look different in character. In 2014, purchases (15) nearly matched sales (16) across 31 transactions, and 2015 was similarly balanced with 17 purchases against 22 sales in 39 transactions. The shift from a roughly even buy/sell mix in 2014–2015 to an overwhelmingly sale-heavy pattern by 2017–2019 is the most visible change in the disclosed history.

Attribution matters here. Of the 252 transactions, 184 are logged as Self, 31 as Spouse, 28 as Joint, 5 as Dependent Child, and 4 Unknown. The non-Self codes should not be collapsed into one actor: Joint entries are not solely attributable to Larson, while Spouse, Dependent Child, and Unknown entries should not be presented as personal trades by him. Any reading of the disclosed activity has to preserve that mix.

What shows up most often, and what it does

Apple appears most frequently in the disclosed record, with 9 transactions (3 purchases, 6 sales), most recently in a transaction dated December 18, 2019 and disclosed January 31, 2020. Danaher and Fortive each appear 7 times, Amphenol 6 times, and HSBC, Kinder Morgan, Mondelez, and Starbucks each appear 6 times. Danaher makes precision instruments and diagnostics equipment used across biotech, life sciences, and clinical labs. Fortive builds instrumentation and workflow software for industrial and healthcare settings. Amphenol manufactures electrical, electronic, and fiber-optic connectors sold into aerospace, defense, and communications infrastructure. Kinder Morgan owns and operates natural gas, refined-products, and CO2 pipeline networks across North America. Mondelez owns global snack brands including Oreo and Ritz. Starbucks operates and licenses coffee retail globally.

By sector, Health Care (28 transactions), Information Technology (26), and Energy (23) lead the classified activity, followed by Consumer Staples (19), Industrials (19), Financials (18), and Consumer Discretionary (16). A further 91 transactions carry no sector classification in the data. Within Energy, Kinder Morgan, TC Energy, Enbridge, and Pembina Pipeline form a recurring cluster of transaction activity involving North American pipeline and midstream infrastructure rather than exploration-and-production companies.

The January 31, 2020 filing covering transactions dated December 18, 2019 is the clearest single event in the supplied transaction records. It lists sale after sale across names spanning technology (Apple, Microsoft, Adobe, SS&C Technologies), industrials (Fortive, RBC Bearings), health care (Danaher, Thermo Fisher, Zoetis, Illumina, UnitedHealth, IQVIA), consumer names (Costco, Home Depot, Mondelez, Constellation Brands), financials (JPMorgan Chase, Mastercard), energy (Kinder Morgan, Enbridge, TC Energy), materials (Alcoa), and real estate (Weyerhaeuser). The disclosed range is $1,001 to $15,000 for most lines, with several $15,001 to $50,000 entries and one line recorded as Unknown. The September 27, 2019 filing covering transactions dated August 15 shows another broad sale pattern, including partial sales across many of the same names.

Earlier in the record, the flow ran in both directions more evenly. Treasury purchases and sales appear repeatedly in 2018 and 2019, alongside name-specific purchases such as Constellation Brands on December 17, 2018 and People's United Financial on February 7, 2019. The named companies span retail and consumer distribution (Costco, Home Depot), payments infrastructure (Mastercard), diversified banking (JPMorgan Chase, Citigroup, Wells Fargo), life sciences tooling (Thermo Fisher, Mettler-Toledo, Illumina), and animal health (Zoetis), a spread that crosses numerous sectors and includes a visible pipeline and midstream cluster in Energy.

Disclosure basis and limitations

This profile is built entirely from congressional financial disclosure filings, which report transaction amounts in dollar ranges rather than exact amounts or share counts. The supplied data includes transactions coded Self, Spouse, Joint, Dependent Child, and Unknown, as reflected in the attribution counts above. Figures for the most frequently disclosed securities measure transaction-row frequency only, while the sector summary is partial because 91 transactions carry no sector classification. The available data is limited to transaction disclosures and does not establish ownership at any later date. The December 18, 2019 transaction cluster appears in the official House filing signed January 31, 2020. The reporting framework includes the STOCK Act of 2012 and the House Committee on Ethics disclosure guide.
